To all whom it may concern:

Be it known that I, FREDERICK VVEs'rnR- BECK, a citizen of the UnitedStates of America, and aresident of the city of St.

in the State'of Missournhave invented certain new and useful Improvements in Sheet-Metal Boxes, of which the following is'a full, clear, andexact description, reference being had to the accompany ing drawings,forming a part of this specification. i v;.

invention relatesito sheet metal boxes such as are commonly used to holdshoe blacking. Boxes of this kind include a cylindrical body and a slipcover having a flange that frictionally engages the wall of the body.The wallof the box body is provided with an outwardly jutting whichserves to limit the downward movement of the cover flange on the bodywall. It is particularly desirable in making such boxes that the wall ofthe box body and the flange of the cover be made as nearly as when thecover flange is fitted to the box body wall, a very close joint will beprovided between these members, so that air may be excluded fromentrance to theinteriorof thebox. Boxes made as closely as possible inaccordance with the foregoing have their covers so closely fitted to thebox body walls as to render it extremely difiicult to remove the coverswithout injury to the box, the difficulty of removal being pronouncedowing to the presence of the stop beads on the box bodies, which, due totheir being located immediately beneath the lower edges of the coverflanges, act to prevent the ready introduction and movement of a sharpimplement between the cover flange and box body wall to loosen theformer from the latter, and permit the removal of the cover.

From the foregoing it will be perceived that it is highly necessary tolocate any means serviceable for the removal of its cover beneath thecontacting portions of the box body wall and the flange of the cover,and also that it is highly important to have such contacting surfaces inparallel lines, as otherwise the binding engagement between the coverflange and the box wall is imperfect.

The box made in accordance with my present invention is constructed withthe object' in view of providing all the desirbead able featuresnecessary to produce a box as nearly as possible air tight, where suchbox. includes a slip cover, the flange of which .is secured to the boxbody wall by frictional engagement only, and provide in such box aconstruction that permits the ready application of a knifeblade, orother sharp implement between the cover flange and thebox body wallforthe purpose of loosening the former from the latter, in

order that itmay beeasily separated therefrom. i

In the accompanying drawings :-A designates the body of my box and B itscover. The box body comprises a bottom 1, and a wall 2,the portion 2 ofwhich hasan outer face extending strictly. in avertical plane. Betweenthelower portion of the box body wall and the upper portion 2 is anoutrron.

wardly jutting head 3 that extends circum ferentially of thevbox and isintended to serve as a stop for the flange of the cover B whensuchflange is fitted to the box body wall portion 9/. The bead'S does notcompletely encircle the'box'body, but is discontinued at a given pointto provide a gap 4:

between endsof the head, which latter are inclined inwardly at theirterminals where they merge into the box body wall at oppo" site sides ofthe gap 4.

The body wall of my the location of'the gap a betweenthe ends of thebeads 3 with an indentation 5, the upper end of which is located at thebase of the cover flange receiving portion 2 of the box body wall. Thisindentation is preferably box is provided at inclined upwardly and alsodownwardly from a point about midway of the height of v v the bead 3,and is adapted to receive the blade of a knife, or other sharpimplement, which may be utilized to separate the flange of the cover Bfrom the box body wall.

The flange 6 of the cover B is so made as to conform at its inner faceas nearly as possible to the outer face of the box body as Would beincurred if the lower edgeof the cover flange were curveduoutwardly tocn--.

form to the upper face ofthestop bead 3 beneath it.

' The flange of the cover B is provided With a downwardly jextendingstraight tongue 7 i that enters into the gap 45 betweenthe ends of thehead 3 when the cover is applied to the box body, andwhich is,therefore, so

located asv to be protected by the bead; and,

furthermore, cause the bead to serve as: a guard that Will preventinjury to. the hands I of a person handling the box to. open it. It

Will be obvious thatinasmuch asithe tongue extends into the gap at; italso occupies a upwardly through the upper end of the. in.-
